# Why didn't deleting files from my external drive free up space?

Files you delete from an external drive go to the Trash, but they stay **on that drive** until the Trash is emptied. Empty the Trash while the drive is connected and the space comes back.

If space still doesn't return:

- An app, or Time Machine's local snapshots of that drive, may still hold the files — give it a little while or restart.
- Hidden system folders on the drive (such as Spotlight's index) use some space.

On the drive Storage Studio uses, don't delete things from its folder by hand — see [why you shouldn't delete from Storage Studio's folder](https://storagestudio.us/faq/external-drives/can-i-delete-things-from-the-storage-studio-folder-on-the-drive).
